Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 and 2: the embodiment discloses a stick formula aluminium water filter equipment flows in accuse, including rose box 1, chute 4 and accuse flow stick 5, the bottom of rose box 1 switches on in the one end of chute 4 through control mouth of a river 2, the messenger one end of chute 4 is equipped with the ejection of compact mouth 3 that is used for connecting casting machine 11, the height that highly is higher than the chute link of 3 casting machine links of ejection of compact mouth, that is to say along the flow direction of aluminium water, the height of ejection of compact mouth 3 increases in proper order, the design of raising has been adopted promptly, can make aluminium water get into casting machine with the mode of overflow like this, and do not destroy the alumina film. In this embodiment, the material of the discharging nozzle 3 is cast iron. Wherein, the filter box 1 is also provided with a filter screen 10 for filtering residual aluminum.
The flow control rod 5 is connected with a flow control rod driving device, and the flow control rod driving device is used for driving the flow control rod 5 to move relative to the control water gap 2 and achieving the purpose of controlling the water gap 2 to be closed or opened according to actual requirements.
The flow control rod driving device of the embodiment is a screw rod 7, the lower end of the screw rod 7 is connected to the flow control rod 5 and is connected to the filter box 1 through threads, and a manual operation device for driving the screw rod 7 to rotate is arranged at the upper end of the screw rod 7. The hand-operated device may be a handwheel 71. When the lead screw 7 is driven to rotate by the hand wheel 71, the height of the lead screw 7 relative to the filter box 1 can be adjusted by thread transmission, and then the position of the flow control rod 5 relative to the water control port 2 can be adjusted.
Because the control mouth of a river 2 needs to cooperate with accuse flow stick 5 and realize sealed and flow control, consequently control mouth of a river 2 also belongs to the vulnerable part, and for the convenience of changing, the control mouth of a river 2 of this embodiment can be dismantled and connect in rose box 1, and both can adopt the mode of chamotte bonding to connect.
